What is SIP Trunking?

Session Initiation Protocol (SIP) trunking has emerged as a popular method of facilitating voice communications over the Internet. SIP trunks are telephone line trunks delivered over the internet using the Session Initiation Protocol (SIP). Using the SIP protocol, telecom service providers (VoIP) can connect legacy PBXs and other voice hardware to Masergy’s Global UCaaS Platform.

SIP Trunking Makes Cloud Migrations Easier

CIOs know business communications are moving to the cloud, but migrating to the cloud all at once can be a risky and expensive proposition.

Masergy understands that most companies don’t want to “rip and replace” their entire phone system. As enterprises move on from the public-switched telephone network (PSTN) and other legacy systems, SIP trunking provides a sound migration path to the cloud, offering many additional advantages including reduced costs, scalable architecture, and enhanced reliability.
